13e-it known that I, 'I RUMAN Bars'ron ci' Cheshire, in thecounty of Newlaven and State of'Oonnecti cu t,liave lnvcnted'a new [Improvement in Water-A Wheels; andI do hereby declare the following, when: taken iu connection withthe =acc'tnnpanying drawings,

and thelettcrs of reference markedtherecn, to be a full, clear, and'exaet description ct' the same, 'and which said drawings constitute. part oi' this speciica- A tion, `and represent in i t Figure 1 a front view, looking from the wheel-pit Figure 2, a top view; y

Figure 3, a section on line 'x x; .and in i Figure 4, a section of the wheel on line 'z s.

Thisinvention relates toan improvement in waterwheeis, thcobjectbei'ng-to reverso the action ofthe wheel whenever occasion requires and dispense with -tlic extensive aud Acomplicated machinery heretofore used for reverwse motion;

, Theuses to which s'nch wheels may be applied are numerous, but I dcsignthis for' raising and lowering, as for mining and similar purposes; and

The invention consists in the' construction of the'. wheel with two sets of buckets, either one of 'which may be used at pleasure, .the water acting upon one A set of buckets to'` turn 4thelwheei in vone direction, and upon theother setito reverse the revolution of vthe wheels, whereby, changingthe' influx of Water4 from one set to another, the power may be reversed. I represent rnyinvention as applied to an overshot` wheeh'as the most convenient mode -oirillustration,

yet' the inventor designs lthe same as also applicable to water-wheels of other forms.

. a' are one set of buckets;

b, a second Seton the same shaft, and this set here represented of equal capacity.'4

Over the wlicel 1s arranged thewater-way A, and two openings all, and over these openings au cscih i lating gate, B,.so as toV close either one ofv thesaidv 4two openings, or both, et, so that but one vof the y openings can be 'opened at the same time.

Erom the pivot of the gate a lever, O, extends to. t a convenient' position 'for operating the-gate.

"Asrepresented in fig.' 2, the gate is. turned to un.- cov'er the opening' d, which admitsavater into the `buckets B, turning thefwheelin'to the direction de` noted by the arrow in iig. 4. i

Now, if the gate ire turned, as denoted bybroken lines, fig. 2, vto close the opening d, and uncover the opening c, then water will be admitted onto the buckets c to cause the wheel to revolve inthe reverse direction, as denoted bythe arrowv in fig. 3.` Thus, as often astlie reverse movement is required, it is only necessary to cut off the water from one wheeh it to the' other; or, to stopthe power en- ..rn thc gate toelose both openings.

' In raising water, this automatic change is preferred,

but in hoisting rocks, minerals,Elize.,` from mines, the

kettle has to remain an uncertaiotime in ,the shaft to be filled, and au automatic actionin changing the clirection of the power is impracticable.l The said changing. must'then he at the williof au operator, and may befelfected bythe miner inthe shaft, or elsewhere, by the'fpullingjot' a rope, and thus moving or reversing lthe wheel.,A During the Asaid vuncertain time, boththe cape elsewhere, or the windlass may be -temporarily detached from the water-wheel.

, As a convenient means for automatically operating the gate, for mining and like lpurposes, I arrange a double rnn'ot' rope I) E, coiled .around .a drum, F, on theIwheei-shaft, so 'thatthe wheel revolving in one cica verse. v t

I arrange a lever, G, upon a pivot, y, with a sheavc,

run,` and also-.a loose s heave, n, for one run, and a similar loose sheave, m, for the other run, the loose at s and t.'

swinging out, andso runsuntil an enlargemenuli, on the other run E, strikes the loose sheave, and

to the position in fig. 3.`

by a connection, H, (see iig. 2,) so that when the lever G isturued, as described, it i turns the gate, and admits water onto the other .set of buckets; then the run is, by an enlargement, or otherdevice on the rope,- operated', as before described, to stop the run; 'then the lever will be turned, asA denoted by broken lines, fig. 3, and close the gate on one side, and open the reverse side, and so continue to do, being governed in its operation by the enlargementsor stops on the ropes. Other devices may he employed for changing the motion.

I claim asmy invention- In a water-wheel, the arrangement of twoindependent sets of buckets, .combined with a device for conducting waterto'the two sets, and so' that the flow of water may be changed'from one set to the other to reversetlie revolution oi' the` wheel, substantially as described .Y v, TR UMAN BRISTOL Y'iitnessew HORACE JOHNSON,
